Diet and Food Guidance for Herpes

No diet has been shown to cure herpes or prevent every recurrence. Good nutrition supports the immune system and healing.

General principles

• Eat regular balanced meals with vegetables, fruit, pulses, whole grains and enough protein.
• Drink plenty of water.
• Include foods rich in vitamin C, zinc and vitamin B, such as citrus fruit, nuts, seeds and legumes.
• Keep a regular sleep routine, which supports immunity.

The lysine and arginine idea

Some people believe that lysine-rich foods help and arginine-rich foods such as chocolate, nuts and seeds trigger cold sores. Research on this is limited and mixed, so treat it as an individual observation, not a rule. If a food clearly triggers your episodes, you may reduce it.

When the mouth is sore

• Choose soft, cool, non-acidic foods such as curd, banana and khichdi.
• Avoid very spicy, salty or sour foods that sting.
• Use a straw for cold drinks if lips are sore.

Ayurvedic dietary view

A pitta-pacifying diet with cooling, light foods is traditionally suggested, and reducing very spicy, fried, sour and fermented food. This is a traditional approach with limited trial evidence.

Be careful with

• Alcohol and smoking, which weaken healing
• Supplements in high doses, which can interact with medicines or harm the kidneys
